XINS is a technology used to define, create, and
invoke remote APIs. XINS is
specification-oriented. When API specifications
are written (in XML), XINS will transform them to
HTML-based documentation and Java code for both
the client-side and the server-side. The
communication is based on HTTP. XINS competes with
the complex SOAP technology. Main design goals
include simplicity, scalability, and testability.
XINS is not only a specification technology, but
also an application development framework. It
offers transaction logging, unique log
documentation, and active code generation.

Restlet is a REST framework for Java. It supports all REST concepts
(Resource, Representation, Connector, Component, etc.) and is suitable

are also available to integrate with Servlet, Spring, Jetty, Grizzly,
Simple, JAXB, JAX-RS, JiBX, Velocity, or FreeMarker. A GWT version is
also available.

EC2 Mobile manages Amazon AWS EC2 instances from a Windows Mobile device. It allows you to start, stop, and manage running EC2 instances. If you have multiple clients who run their services on EC2, you can also store multiple profiles so that you can see all of the instances running across all clients. Similarly, you can see each profile's AMI images.

Jmx4Perl provides an alternate way of accessing Java JEE Server management interfaces that are based on JMX (Java Management Extensions). It is an agent-based approach where a small Web application deployed on the application server provides HTTP/JSON-based access to JMX MBeans registered within the application server. It is set up from a handful of Perl modules, which can be integrated seamlessly in your own programs. It also includes a Nagios plugin, check_jmx4perl, a jmx4perl command line tool for remote JMX queries and operations, and a readline-based JMX shell j4psh, with context sensitive command completion and syntax highlighting.

DooPHP is a very fast PHP framework. It enables developers at all levels to rapidly develop robust Web 2.0 applications. It is quite feature rich. DooPHP supports some common stuff found in a Web framework, such as an MVC-base structure, RESTful APIS, a REST client, URI routing, database ORM tools, a model generator, HTTP Digest Authentication, a flexbible compiling template engine, logging and profiling tools, and more.

Aeson allows very easy marshalling of POJOs (Java objects) to JSON. Since it uses JAXB annotations, you can marshall all your JAXB-annotated classes to JSON without any modifications. The library is very small, and only relies on core J2SE (1.5 and up) and JAXB.
